Depends on #2555 and #2721 and all their dependencies.

This is still very WIP, but I wanted to publish it anyways.

mhm.. is there a reason it's nowhere noted what this function actually does?

Because this PR is still WIP :-) It handles the PI (prefix information) option, which disseminate a prefix through a sub-net.

Does this PR still depend on another one?

miri64 commented May 10, 2015

Yes, but one that isn't open yet. This PR is WIP, it needs thorough clean-up and only implements router discovery. I'll open a PR for the Address Resolution in the next few days, but it will depent on #2908 and #2909

Actually, the PR I spoke about is already open: #2910

Why does this comment say as defined above, when the only definition “above” is actually in RFC 4861? When I first read that comment, I expected there to be a typedef'd enum which contained all possible flags, and the type of flags to be ng_ipv6_nc_config_flags or something rather than uint8_t... Would that make sense or am I missing something here?
(After skimming through RFC 4861, I'm assuming flags refers to the M and O flags...)

It's a problem in general to reference a group of flags in doxygen. The defines prefixed with NG_IPV6_NC_... in the document group "Flag definitions for ng_ipv6_ref_t are meant. I'm against using enums for flags (see #2614 (comment) on that note). Have you maybe a better solution for referencing them?

This PR contains only router discovery. I will rebate it to #2910 as soon as that one reaches some maturity.
